Homework Worksheet - Ionic Nomenclature

Write this in your notes Latin Names Some compounds were given Latin names before systematic nomenclature was created These are still in use even today On cations with two primary oxidation states, a suffix indicates the oxidation state suffix "–ic" means higher oxidation state suffix "–ous" means lower oxidation state Most often used on elements with Latin names

Example of Latin Name In Latin, iron is called ferrum This is why its atomic symbol is Fe Iron has two primary oxidation states, +3 and +2 Fe+3 is called ferric Fe+2 is called ferrous

What is this called? A ferrous wheel!!!

Example of Latin Name In each oxidation state, Fe can be combined with O Fe2O3 is ferric oxide FeO is ferrous oxide

Latin Names Latin names are most frequently used with iron, copper, tin and lead, but can be used with any element Systematic Name Latin Name iron (III) oxide ferric oxide iron (II) oxide ferrous oxide copper (II) oxide cupric oxide copper (I) oxide cuprous oxide tin (IV) oxide stannic oxide tin (II) oxide stannous oxide lead (IV) oxide plumbic oxide lead (II) oxide plumbous oxide
